Audited Supplier 630A 4p Automatic transfer switch with ATS controller delay time undervoltage over voltage
Features:
1) Provided with such protective functions as checking two sources of voltage at
the same time, protection when any one phase or one phase above experiences
under- or over-voltage, guide phase
2) When two sources have abnormal or faulty tripping (overload, short circuit),
the controller won't send out the order to realize the protective function of
reopening and closing
3) Four working modes: automatic control, common source (power supply I),
standby power supply (power supply II), breaking electricity (re-tripping
4) When the working mode is in the automatic control state, it has two
self-throw no self-recover, self-throw, and self-recover functions:
a) Self-throw non-self recover: when the device enters the working state, power
supply I automatically throws into supplying electricity; when power supply I
has an abnormity, it will automatically transfer to power supply II; when power
supply I recovers, it doesn't transfer until power supply II has an abnormity,
then it will automatically transfer to power supply
b) Self-throw and self-recover: when the device enters the working state, the
common source throws into supplying electricity; when power supply has an
abnormity, it will automatically transfer to standby power supply; when common
power supply recovers, it will automatically recover common power supply; but
when the standby power supply has an abnormity, the controller will emit an
alarm sound
